Benefits of Merino Wool
Moisture Wicking
Merino wool is the best fiber to regulate moisture. It does this by absorbing sweat from your skin and releasing it into the air. Whether you're hiking, running, biking, on the job, or just relaxing at home, our wool helps keep you dry and comfortable all day long.
Soft & Comfortable
Merino wool fibers are much finer than traditional wool, creating a luxuriously soft feel that won’t itch or irritate your skin. Comfortable enough for everyday wear and gentle enough for sensitive skin, it’s a natural choice for underwear, base layers and next-to-skin comfort.
Highly Breathable
Merino wool’s unique structure allows air to circulate freely, helping to regulate your body temperature in both hot and cold weather conditions. Whether you're layering up for winter or staying cool in summer, Merino keeps you comfortable by letting your skin breathe.
Anti-Microbial
Merino wool naturally resists odor-causing bacteria, keeping you fresher for longer. No lingering smells, even after extended wear. Perfect for travel, outdoor adventures, and everyday life.
Insulates When Wet
Merino wool can hold up to 30% of its weight in moisture without feeling wet or clammy against the skin. Unlike cotton or synthetic fabrics, it keeps insulating when damp, making it a smart choice for unpredictable weather and high-output activity.
Fire Resistant
Merino wool is naturally fire-resistant and self-extinguishing. It will not melt or stick to your skin like synthetic fabrics. A trusted option for first responders, campfire safety, or any high-heat environment.
UV Protection
Our Merino wool clothing helps protect you from the sun’s harmful rays, with different levels of UPF based on fabric weight:
-
Microweight (145 GSM): UPF 20
-
Lightweight (170 GSM): UPF 25
-
Midweight (235 GSM): UPF 50+
-
Heavyweight (400 GSM): UPF 50+
These natural UV-blocking properties make Merino wool ideal for long days or the beach or above treeline.
Renewable and Sustainable
Merino wool is a natural, biodegradable fiber with a low environmental footprint. Grown by Australian Merino sheep and shorn seasonally, it is a renewable material that supports responsible farming practices.

A SOCK OVERHAUL
We got our sock machines set up in May of 2019, and hit the ground running. We knew our customers wanted a sock for every occasion, with heights and cushion levels for all activities. By combining our historic textile knowledge, and using what we learned after redesigning our classic sock styles, we were able to envision a brand new sock collection that could truly meet your needs.
YARN SELECTIONS

WOOL/NYLON YARNS
We dialed in our yarn selection, using a combination of merino/nylon as the main body of the socks. These yarns deliver a high merino wool content, with the extra durability of nylon.

HIGH WOOL CONTENT
We have packed in huge quantities of wool next to your skin, using the synthetics only as needed to improve fit and durability.

TECHNICAL FEATURES
Stretch nylon yarns are light enough to keep the merino content high while giving shape and fit to the sock. Lightweight plating also adds durability to high wear zones on the heel and toe.
You don't know how grateful I am for these Merino Wool socks. I bought them because they said they were breathable, and I found out when my son wore them to his soccer game. I cut the bottom of the team socks off so he could wear the merino ones. His team socks make him sweat a lot, causing blisters, but since he started wearing them, his feet have been drier, and it has helped keep his blisters from getting worse. I had tried everything from creams to other socks, even buying him more comfortable cleats, but my son's feet sweat a lot, and nothing has helped with his blisters. What I like most is that my son likes wearing them and hasn't complained that they bother him at all. So, I will buy more.
Thank you for taking the time to share your son's experience with our Microweight Cushion - Mini Crew Wool Socks! We are thrilled to hear that they have helped keep his feet dry and prevent blisters during his soccer games. Our Merino Wool socks are designed to be breathable and comfortable, so we are glad to hear that your son enjoys wearing them. We appreciate your support and look forward to providing more high-quality socks for your family in the future.
Kindly,
